老年病人因免疫监督系统减弱等原因恶性肿瘤的发病率较高。当内脏发生恶性肿瘤时所出现的皮肤表现称为肿瘤性皮肤病(Paraneoplastic dermatoses)。这些皮肤表现经常在恶性肿瘤之前出现,提高对伴肿瘤性皮肤病的认识和警惕,无疑对恶性肿瘤的早期诊断和早期治疗是非常有意义的。因限于篇幅仅将笔者在工作中诊治过的老年前期及老年期伴肿瘤性皮肤病病例作一些介绍,以供同道参考。 Elderly patients have a higher incidence of malignancy due to weakened immune surveillance systems. The skin appearance that occurs when a malignant tumor develops in the viscera is called paraneoplastic dermatoses. These skin manifestations often appear before malignant tumors. Raising awareness and vigilance on neoplastic dermatosis is undoubtedly very significant for the early diagnosis and early treatment of malignant tumors. Due to space limitations, only the cases of pre-senile and elderly patients with neoplastic dermatosis diagnosed and treated at work were introduced for reference.
